Folha de exercícios de multiplicação com dominós para imprimir

Create a vertical printable educational worksheet in Brazilian Portuguese, clean white background, playful classroom design, centered composition, bold rounded typography, bright kid-friendly colors. At the very top, a large navy-blue headline reading {argument name="headline text" default="DOMINÓ DA MULTIPLICAÇÃO"}, with small yellow decorative rays on both sides. Below it, a purple ribbon banner with white uppercase text reading {argument name="subtitle text" default="CONECTE A CONTA AO RESULTADO!"}. Under the banner, add two centered instruction lines in black: "Recorte as peças e embaralhe. Cada jogador pega 7 peças." and "O objetivo é ficar sem peças!". The main area shows 40 domino-style tiles arranged in a 4-column by 10-row grid, evenly spaced.

The left half contains either a number result or the word "INÍCIO" on the first tile, and the right half contains a multiplication expression. Use alternating border colors across the grid such as purple, green, blue, orange, pink, and yellow. The 40 tiles, in row order from left to right, top to bottom, are: 1) "INÍCIO | 1 × 1", 2) "1 | 1 × 2", 3) "2 | 1 × 3", 4) "3 | 1 × 4", 5) "4 | 1 × 5", 6) "5 | 1 × 6", 7) "6 | 1 × 7", 8) "7 | 1 × 8", 9) "8 | 1 × 9", 10) "9 | 2 × 2", 11) "4 | 2 × 3", 12) "6 | 2 × 4", 13) "8 | 2 × 5", 14) "10 | 2 × 6", 15) "12 | 2 × 7", 16) "14 | 2 × 8", 17) "16 | 2 × 9", 18) "18 | 3 × 3", 19) "9 | 3 × 4", 20) "12 | 3 × 5", 21) "15 | 3 × 6", 22) "18 | 3 × 7", 23) "21 | 3 × 8", 24) "24 | 3 × 9", 25) "27 | 4 × 4", 26) "16 | 4 × 5", 27) "20 | 4 × 6", 28) "24 | 4 × 7", 29) "28 | 4 × 8", 30) "32 | 4 × 9", 31) "36 | 5 × 5", 32) "25 | 5 × 6", 33) "30 | 5 × 7", 34) "35 | 5 × 8", 35) "40 | 5 × 9", 36) "45 | 6 × 6", 37) "36 | 6 × 7", 38) "42 | 6 × 8", 39) "48 | 6 × 9", 40) "54 | 7 × 7". At the bottom, add a large rounded dashed purple box spanning most of the width. Inside the left side of this box, place the section title "COMO JOGAR:" in bold purple uppercase, followed by 5 bullet points in black: "Coloque a peça “INÍCIO” na mesa.", "Os jogadores, na sua vez, devem encaixar uma peça cuja conta seja igual ao número da ponta livre.", "Se não tiver peça para jogar, compre do monte.", and "Vence quem ficar sem peças!". On the right side of the same box, add the title "EXEMPLO DE INÍCIO:" in purple uppercase and show 4 small domino tiles in sequence plus ellipsis: "INÍCIO | 1 × 1", then "1 | 1 × 2", then "2 | 1 × 3", then "3 | 1 × 4", followed by "...". Keep the overall style crisp, vector-like, printable, friendly for elementary math practice, with balanced spacing and highly legible text.
